Energy Proportionality and Workload Consolidation for Latency-Critical Applications

Edouard Bugnion, Christos Kozyrakis, Georgios Prekas, Mia Primorac

Energy proportionality and workload consolidation are important objectives towards increasing efficiency in large-scale datacenters. Our work focuses on achieving these goals in the presence of applications with microsecond-scale tail latency requirements. ...

Energy-Efficient Co-Design Optimization of Many-Core Platforms for Big-Data Streaming Applications

Karim Kanoun

Big-Data streaming applications are used in several domains such as social media analysis, financial analysis, video annotation, surveillance, medical services and traffic prediction. These applications, running on different types of platforms from mobile ...

CSMA/CA in Time and Frequency Domains

Patrick Thiran, Julien Pierre Sacha Herzen

It has recently been shown that flexible channelization, whereby wireless stations adapt their spectrum bands on a per-frame basis, is feasible in practice. In this paper, we propose TF-CSMA/CA, an algorithm for flexible channelization that schedules packe ...

Flexible Spectrum Assignment for Local Wireless Networks

Julien Pierre Sacha Herzen

In this dissertation, we consider the problem of assigning spectrum to wireless local-area networks (WLANs). In line with recent IEEE 802.11 amendments and newer hardware capabilities, we consider situations where wireless nodes have the ability to adapt n ...

Packet Scheduling in Multicamera Capture Systems

Pascal Frossard, Laura Toni, Thomas Maugey

In multiview video services, multiple cameras acquire the same scene from different perspectives, which results in correlated video streams. This generates large amounts of highly redundant data, which need to be properly handled during encoding and transm ...

IX: A Protected Dataplane Operating System for High Throughput and Low Latency

Edouard Bugnion, Christos Kozyrakis, Georgios Prekas

The conventional wisdom is that aggressive networking requirements, such as high packet rates for small messages and microsecond-scale tail latency, are best addressed outside the kernel, in a user-level networking stack. We present IX, a dataplane operati ...

Correlation-Aware Packet Scheduling in Multi-Camera Networks

Pascal Frossard, Laura Toni, Thomas Maugey

In multiview applications, multiple cameras acquire the same scene from different viewpoints and produce correlated video streams. This results in large amounts of highly redundant data. In order to save resources, it is critical to handle properly this co ...

Near Optimal Work-Stealing Tree Scheduler for Highly Irregular Data-Parallel Workloads

Martin Odersky, Aleksandar Prokopec

We present a work-stealing algorithm for runtime scheduling of data-parallel operations in the context of shared-memory architectures on data sets with highly-irregular workloads that are not known a priori to the scheduler. This scheduler can parallelize ...
